Release Notes IDS NXT 2.5

Introduction

These release notes describe the new features and changes in the IDS NXT 2.5 release. The release includes the following components:

IDS lighthouse 2.5

You find the release notes for IDS lighthouse directly in IDS lighthouse: https://ids-lighthouse.ai/login/

IDS NXT OS 1.4.0

You find the release notes for IDS NXT OS 1.4.0 under Release Notes for IDS NXT OS 1.4.0

IDS NXT cockpit 2.4.0

This version of the IDS NXT cockpit supports Windows 10 64-bit (version 21H1, 20H2, 2004, 1909).

Note: The IDS NXT cockpit 2.4 cannot be used to operate an IDS NXT vegas camera. Use the IDS NXT Cockpit 1.2.4 instead for the IDS NXT vegas models.

New and changed functions

New camera features: We extend the existing camera parameters with IDS NXT cockpit 2.4.0. From now on, new parameters are available in addition to the known functions (prerequisite: IDS NXT OS 1.4.0 or higher is installed on the camera). These are:
- 2x2 and 4x4 binning
- Gamma correction (in the extended gain settings)
You can limit the image directly on the sensor in the new "Sensor ROI" area. This means that only the specified image detail is read out and processed, resulting in lower memory usage and faster processing times.
Use the linescan mode if you want to check rotationally symmetrical objects, for example. You can use the linescan mode to continuously capture narrow areas of your rotating object, for example. These areas are combined directly on the camera to make an image. With the Linescan mode, you can thus "unwind" the shell of your test specimen, for example, and display it as a 2-dimensional image. Then you can analyse this image directly on the camera with the help of a vision app.
The backup function allows you to create a backup and save your camera's data. You can also load the backup file to an identical IDS NXT camera to transfer your installed apps and configurations to other IDS NXT cameras.

General improvements

Fixed the memory leak that caused excessive load on the main memory during continuous operation of the IDS NXT cockpit.
The update of the camera firmware has been accelerated.
The memory usage of vision apps is displayed in the VApp Manager.
Added progress bars in the graphical interface when uploading or downloading files.
Fixed a bug that prevented images from being saved using a file path with a "." (dot).

Object Detector 2.0.4

You can define one or more ROIs (region of Interest) in the Object Detector. Within the ROIs, objects at any position are identified by means of detection.
The results output via the REST interface has been adapted to represent ROIs.
The information on the ROIs was added to the result XML file. The result XML file is transferred via FTP together with the images.
Fixed a bug that could cause incorrect results after switching a CNN (convolutional neural network).

Classifier 1.3.10

The vision app has been updated for the camera feature "Binning", so that an already set ROI will be updated when you enable binning.

CNN Evaluator 2.4.7

Fixed a bug that prevented the result JSON file from being downloaded from the vision app web page on Microsoft Edge.

OPC UA Server 1.3.0

Support of the new camera functions binning, gamma correction, sensor ROI and linescan mode. Prerequisite: IDS NXT OS 1.4.0 or higher is installed on the camera.

IDS NXT Vision App Creator 1.4.0

The IDS NXT API has been updated to version 2.4.0 so that you can program vision apps for IDS NXT OS 1.4.0.
Vision app and plugin templates have been updated, e.g. support for vision app web pages.
The source code samples for vision apps are now available on GitHub: https://github.com/ids-imaging/ids-nxt-vision-app-examples
A bug has been fixed so that Oracle Virtual Box can also be used in version 6.1.20 or higher.

Known issues

IDS NXT cockpit	Vision App "Crawler" is no longer usable.	The separate vision app "Crawler" is no longer compatible with IDS NXT cockpit 2.3.0 or higher, as the Crawler application has been integrated into IDS NXT cockpit from version 2.3 on.
IDS NXT cockpit	Icon for Crawler is displayed 2x in IDS NXT cockpit.	If the vision app "Crawler" is still installed on the camera after an update to IDS NXT cockpit 2.3, the crawler icons are displayed 2x in the IDS NXT cockpit. Uninstall the previous vision app "Crawler" on the camera.
IDS NXT cockpit	Image flipping and ROI configuration file	If you flip the image after you have created ROIs, the positions of the ROIs are not saved correctly in the ROI configuration. Flip the image first. Afterwards, set the ROIs. Save the ROI configuration.
IDS NXT cockpit	Mixed operation of IDS NXT cockpit and IDS peak	In the case of mixed operation with IDS peak, uninstalling IDS peak or IDS NXT cockpit may lead to complications when updating the GUF files. After uninstalling, reinstall the remaining software to fix the problem.
IDS NXT cockpit	Vision apps and previous ROI feature	If vision apps are still using the previous ROI feature, the ROI may show an incorrect position when switching binning.
IDS NXT OS	IDS NXT cameras with IDS NXT OS version 1.0	If you still have an IDS NXT camera with IDS NXT OS version 1.0 and set a prescaler or delay in the hardware trigger settings, these settings also affects all other operating modes: software trigger freerun (continuous software trigger)
IDS NXT OS	Maximum frame rate in freerun mode	To achieve the maximum frame rate in freerun mode, no images should be displayed with the IDS NXT cockpit due to performance reasons.
IDS NXT OS	Vision apps and sensor ROI	Rarely, reducing the sensor ROI may cause a restart of the vision apps.
Object Detector	Result display	Japanese characters cannot be displayed in the result image.
Classifier	Result display	Japanese characters cannot be displayed in the result image.
OPC UA Server	New installation of a vision app	After reinstalling a vision app, it may be necessary to call the "PrepareRecipe" method twice to enable the corresponding recipe. Alternatively, after reinstalling a vision app, it is recommended to start it once initially.
OPC UA Server	Highlight results	If vision apps use formatted or "highlighted" results, at least version 1.2.0 of the OPC UA Server is required.
OPC UA Server	Multi ROI configurations	Multi ROI configurations are only supported from OPC UA Server version 1.2.0 on.
GPIO Gateway	No support for CNN manager as of version 2.1.4	From version 2.1.4 on, the CNN manager vision app is no longer supported in combination with the GPIO Gateway vision app.
CNN manager	No support as of IDS NXT OS 1.1	The CNN Manager vision app is discontinued for IDS NXT OS 1.1 or higher. For cameras with IDS NXT OS 1.1 or higher, the newly revised and enhanced Classifier vision app replaces the CNN manager.
IDS NXT Vision App Creator	Update of the IDS NXT Vision App Creator	After an update, the setting of the alternative "Source Folder" for projects must be reset.
IDS NXT Vision App Creator	Update the virtual machine	During the update, the virtual machine is deleted and replaced by a new one. Before updating, you must manually back up files that you have stored in the previous virtual machine and want to use further.
IDS NXT Vision App Creator	Uninstallation	The installation of the IDS NXT Vision App Creator does not require administrator privileges. If you installed the previous version as an administrator, the uninstall entry in the Control Panel may not be removed automatically. Go to "Control Panel" → "Programs and Features" and uninstall the previous version of IDS NXT Vision App Creator here.
IDS NXT REST interface	Wrong return value in case of incorrect authentication	If you use an incorrect authentication for a request via the IDS NXT REST interface, the request fails. Here, the corresponding error code "401 Unauthorized" is not always returned, but also other error codes that do not clearly indicate the incorrect authentication. This bug will be fixed in a later version.
